Hi,
This patch removes the struct sock parameter from ip6_route_output();
looking at the ip6_route_output() implementation in net/ipv6/route.c
will show immediately that it is not used in this method.

In fact, icmp.c and ip6_output.c are the only places in the kernel
where the sk (struct sock) parameter passed to ip6_route_output() is not NULL;
anyhow, as explained above, this parameter is unused; changing
the ip6_route_output() prototype by omitting the struct sock parameter
does not break anything.
